This is a single Dosing Ring 53mm Black. We also have silver, 51mm, and 58mm in stock, so please inquire. The third image shows 51mm/53mm/58mm from the front right. This is a dosing ring (funnel) for espresso. It is a ring that is placed on top of the portafilter to make it easier to catch the powder coming from the grinder, effectively preventing the scattering of coffee powder. Magnets are embedded in the ring, which adheres to the metal filter and does not easily fall off. This 53mm bottom diameter is for espresso machines with a 53mm filter diameter, such as Saeco and Starbucks (Saeco OEM), but please confirm the compatibility before purchasing. The item is new and unused, but please refrain from purchasing if you are sensitive to minor imperfections or if you are looking for an unopened, brand-new product. 【Specifications】 Material: Aluminum, Magnet 53Φ Size/Weight: Outer diameter: 64mm / Ring outer diameter: 53mm / Overall height: 22mm / Weight: 37g (Reference) 51Φ Size/Weight: Outer diameter: 62mm / Ring outer diameter: 51mm / Overall height: 22mm / Weight: 34g 58Φ Size/Weight: Outer diameter: 70mm / Ring outer diameter: 58mm / Overall height: 22mm / Weight: 41g Shipping costs will be discounted only when combined with other items.
